- and combination of the various parts of the guides for the master-wheel.

. thereon.

Be it known that I, IRA A. JEFFERSON, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and Improved Horse-Power, of which the follow- The object of my invention is to provide an improved horse-power, especially adapted for use at mines, which. is compact and portable, and in which the controlling mechanism can be operated from without the path of the sweep.

The invention consists in the construction horse-power, part being brokenout to disclose the construction of parts. Fig. 2 is a sectional elevation of the same on the line 00 m, Fig. 1. Fig. 3 is a detail view showing the Fig. 4is an enlarged sectional elevation on the line'y y, Fig. 1. Figs. 5 and 6 are detail views showing the arrangement of the controlling mechanism.

A represents the frame of the machine, composed of corner-posts A and connecting side beams, A A detachably united by mortise or other joints if of wood, or bolted together if of 1ron..

The base B, upon which the frame A is erected, is constructed of four side beams, united at their ends, and the two upper parallel beams, B, bolted or otherwise secured Upon the beams B are erected the standards 0 O, of which 0 is the higher, and .in bearings in said standards revolves the drum-shaft D, carrying the drum D, having wide peripheral guide-flanges, so that the rope can be coiled in layers thereon, and hence wound more rapidly as the coils increase.

The construction of the base enables the drum to be placed directly over the mouth of a mining-shaft, as shown in Fig. 2.

On the drum-shaft D is mounted thebrakewheel E and ratchet-wheel F, revolving with Serial No. 194,849. (No model.)

the drum D, and formedintegrally therewith or attached thereto, and on the projecting end lower end with the laterally-projecting arm H so that by swinging said arm H horizontally the clutch-collar H can be engaged with and disengaged from the clutch-head G of the gear-wheel G, and hence said gear-wheel locked on the drum-shaft or the reverse.

Over the before-mentioned brake-Wheel E The vertical clutch-bar H is provided at its is passed the brake-band E, one end ofwhich I is secured by a staple, E", or other suitable means to the base of the machine, and the other end is connected to the outer .end of the arm Iof the shaft I, mounted to rock in bearings KK,arranged upon the upper base-beam, B, or a plate, J, bolted thereon and attached to the corner-post A, respectively, as shown in detail in Fig. 5. The rock-shaft I is also provided with the outer and opposite crankarm, 1.-

With the ratchet-wheel F on the drum shaft engages the angle-lever pawl or dog L, pivoted at its angle to and between cars or lugs L on the base-plate J ,carrying the brake-shaft, and

the lower arm, L, of said angled dog is acted upon by the cam-rod M, formed integrally with or attached to the inner end of the rockshaft M, mounted to turn in bearin gs upon the base-plate J and post A. The shaft M is also provided with the outer crank-arm, M so that by swinging said arm M the lower arm, L, of the angled dog is raised and the pawl L disengaged from the ratchet-wheel F.

The outer end of the arm H of the clutchbar H and the crank-arms I and M are connected by rods N (shown in Fig. l) with manipulating-levers N, pivoted to a suitable support outside of the path of the sweep. Thus by operating the proper lever, N the brakel the frame of the machine constructed detach- 5 5 band E can be applied upon its wheel or released therefrom, the ratchet-wheel F disengaged from its pawl, or the gear-wheel G thrown in or out of action with the drumshaft to stop or start the motion ofthe drum, as may be desired. The teeth 'of the loose gear-wheel G continually'engage the spurteeth of the double gear-wheel O, mounted on the shaft 0, rotating in bearings O O on the top of the standard 0 and in the center of the upper connecting-beam, A of the frame A, respectively, said beam or bar A being curved or bent outwardly to accommodate the double gear-wheel O, as shown. The bevel-teeth of the double gear-wheel O mesh into the teeth of the bevel master-Wheel P, mounted to revolve upon a short vertical shaft, P, received in a central bearing in the cross-frameQ, bolted or otherwise secured on either side to opposite connecting -beams, A of the frame A. The shaft P is supported upon the, cross-frame Q by the collar Q, which also serves as a hearing for the master-wheel.

The master'wheel is provided with ears P between which the sweep is received, and is held in engagement with the double gearwheel 0 by means of guides R, bearing upon the upper flat surface of the masterwheel at its periphery, and having vertical arms or extensions R bolted to the upper ends of the posts A at either side of the point of engagement with the gear-wheel 0. With this construction when the sweep is carried around and the clutch operated the drum is rapidly revolved, owing to the proportions of the connecting-- gearing, and the hoisting speedily accomplished.

The drum can be set in motion or instantly checked from without the sweep-circle, the motion can be retarded, or the ratchet-wheel released and the drum allowed to rotate freely in the reverse direction, to permit of unwinding the hoisting-rope for a new load, as desired, by the operator.

Owing to the central location of the masterwheel over the drum the machine is rendered extremely compact, and the parts being detachably united the whole can be readily taken apart and packed for transportation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a horse-power, the combination, with ably, substantially as shown and described, of the drum D, mounted to revolve centrally therein, the loose gear-wheel G, adapted to be locked on the drum-shaft, the double gearwheel 0, engaging with said gear-wheel G, and the master gear-wheel P, mounted to revolve on the frame Q above the drum and engaging with the double gear-wheel 0, substantially as specified, whereby compactness and portability are obtained, as set forth.

2. In a horsepower, the combination, with the drum-shaft D and the loose gear-wheel G thereon, driven by gearing from the masterwheel, of the clutch-collar H on the drumshaft, arranged to engage said gear-wheel G, the vertically-mounted clutch-bar H having arm H the connecting-rod N, and the operating-lever N, pivoted outside of the path of. the sweep, substantially as and for the pur: pose set forth.

3. In a horse-power, the combination, with the brake-wheel E on the drum-shaft, of the brake-band E, having one end attached to a fixed support, the rock-shaft I, having the arm I connected with the free end of said brake-band and provided with the crank-arm P, the operating lever N, and the rod N, connecting said lever with the crank-arm 1, substantially as shown and described.

4. In a horse-power, the combination, with the ratchet-wheel F on the drumshaft, of the angle-lever pawl L, the rock-shaft M, having cam-arm M acting on the arm L of the anglepawl, and the operating-lever N, connected by a rod, N, with the arm M of the shaft M, "substantially as and for the purpose set forth.

5. The combination, with the frame A of the horse-power, mounted upouthe base B B, and the standards 0 G,erected upon the base, of the drum-shaft D, revolving in hearings on said standards, the flanged drum D, provided with brake-wheel E and safety ratchet-wheel F, the loose gear-wheel G on the drum-shaft,

the double gear-wheel O, the beveled masterwheel P, held in engagement with the same by guides R, and means for operating the cl utchbrake band and safety-pawl from without the path of the sweep, substantially. as herein shown and described.
